Beta-glucan is a major growth substrate for human gut bacteria related to Coprococcus eutactus. Beta-glucan is a major growth substrate for human gut bacteria related to Coprococcus eutactus

The gut bacterium Coprococcus sp. ART55/1 has been found to encode two genes containing glycoside hydrolase family 9 (GH9) catalytic domains. These genes are hypothesised to impact upon the ability of this bacteria to utilise different carbon sources. To further investigate the role of these genes, as well as the wider transcriptome, Coprococcus sp. ART55/1 was grown on five different carbon sources - beta-glucan, lichenan, cellobiose, glucose and glucomannan - and the transcriptional response was investigated using RNA sequencing.
